TECHNETIUM-99M-HMPAO SPECT IN STURGE-WEBER SYNDROME

Technetium-99m-HMPAO interictal SPECT was performed on three pediatric patients with Sturge-Weber syndrome (SWS). Results: Brain SPECT of al l three patients demonstrated markedly diminished tracer localization in the affected hemisphere. In one patient, the SPECT abnormality was more extensive than the associated abnormalities on CT and MRI. Conclu sion: Technetium-99m-HMPAO brain SPECT can detect cerebral perfusion a bnormalities associated with SWS and deserves consideration in the ima ging evaluation of SWS patients.
